Until a century ago, bloodletting was used to treat many ailments. Dating back to before the time of Christ, the treatment involved letting a type of worm, called a leech, such blood from the patient. People believed that there were liquids called humors in the body and that these determined a person’s personality and heath. Bloodletting, they thought, restored a balance to these humors.

At the time, little was known of the working of the human body, but people did know that the same liquid, blood, flowed throughout everyone’s body. They knew it was a vital substance, for loss of any great amount of it meant certain death. Thus, they concluded that all diseases were carried in the bloodstream, and that if the body was relieved of bad blood, heath would return. Bloodletting, however, came to be used as a cure-all. Woman were bled to keep them from blushing while members of the clergy were bled to prevent them from thinking sinful and worldly thoughts.

From the 11th to the 18th centuries, barbers were the people to go to if you needed to be bled. This custom explains the significance of the traditional barber’s pole: the white stripes stand for bandages and the red stripe for blood.

1. This passage is concerned about            .

healthy people and doctors                         B. bleeding as a cure-all

C. barbers of long ago                                      D. leeches with special jobs to do

2. The red and white stripes on barber pole symbolize         .

sin and redemption                             B. the bleeding form

According to new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs.

The farm animals, who are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel.

The recent study, the results of which were published in the journal Royal Society; Open Science, show the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.

Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the images for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent—the same rate at which a human’s ability to perform the same task declines,

“Anyone who has spent time working with sheep will know that they are intelligent and individual animals who are able to recognize their handlers.” said Professor Jenny Morton,　 who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, close to those of humans and monkeys.”

Recognizing faces is one of his most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, affect this ability.

“Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington’s disease that develop over a long time and affect cognitive (认识的) abilities. Our study gives us another way to monitor how these abilities change.” Morton said.

1.According to the new research, what’s unusual about sheep?

A. They have large brains.

B. They can recognize their owners.

C. They can tell animals from humans.

D. They can recognize human faces from photographs.

2.How did the researchers train the sheep?

A. By giving food rewards.

B. By showing photos of famous people.

C. By guiding them to follow their handlers.

D. By showing photos of humans and monkeys by turns.

3.What can be inferred from the passage?

A. Sheep have a higher face-recognition ability than monkeys.

B. The new discovery is of great benefit to the study of cognitive ability changes.

C. The sheep’s face-recognition ability may prevent some disorders of the brain.

D. The sheep’s face-recognition ability stays the same when shown photos at any angle.

4.What’s the best title of the passage?

A. A Wonderful Scientist

B. The Life of Sheep

C. A New Discovery about Sheep

D. How Sheep Recognize Each Other

The team of researchers from the University of Lincoln, UK, is designing and building an app to help farmers in hot climates identify and record the spread of locusts(蝗虫) on their land.

By recognizing locusts through the smartphone’s camera, the app will be able to identify the stage of the insect's growth and record its location. This information can then be utilized so that the farmers can use pesticides(杀虫剂) more accurately in the early stages of their life time, greatly reducing the amount of crop damage.

This approach could also reduce remaining pesticide levels, leading to increased food safety while maintaining food security and protecting nearby water systems.

“Each year, approximately 18 million hectares of land are damaged by locusts, influencing hugely farmers and their productivity, explains Dr. Bashir Al-Diri from the School of Computer Science at the University of Lincoln.” Their monitoring techniques currently rely on field surveys by people through digging insect eggs, but this information only helps farmers to make mid and long-term forecasting decisions and can delay effective management measures. By digitally recording the exact number, age and location of locusts, we hope this new app will put more knowledge and more power into the hands of the farmers.

Dr. Al-Diri and his team of computer scientists work with the Lincoln Institute for Agri-food Technology at the University of Lincoln, aiming to support and improve productivity, efficiency and farming through research, education and new technology.

With advanced technology, the developers hope that the app will also be used for a wide range in the future to capture and document information about the natural world. For example, it could easily be adapted to help individuals identify plant diseases or to digitally capture the number and type of birds and wildlife in specific locations as part of national and international surveys.

1.What do we know about the app mentioned in the passage?

A.It has helped farmers record the spread of locusts.

B.It will be of great use for farmers in hot climates.

C.It may cost the farmers more than they expect.

D.It will remind farmers of what the locusts look like.

2.Which can replace the underlined word "utilized” in the passage?

A.Accessed. B.Controlled.

C.Arranged. D.Progressed.

3.What can we know according to Dr. Bashir Al-Diri?

A.Farmers don't know how to deal with locusts.

B.Their techniques can be used to dig insect eggs.

C.Farmers suffer greatly because of locusts.

D.Some steps must be taken before using the app.

4.What is the purpose of Al-Diri and his team?

A.To check if the app is useful in killing locusts.

B.To educate farmers on how to protect themselves.

C.To assist in raising agricultural production level.

D.To direct farmers to change their farming methods.

Plants do not listen to the radio. But a team of researchers in Greece recently found a way to turn lemons into very small “radio stations” that can broadcast information about their trees’ moisture content to a smartphone—the first step toward creating what the researchers call an “Internet of plants.”

Scientists had previously attached sensors to trees to measure their water use, but “no other team had created a wireless radio network among plants, sending information while consuming only a few microwatts and costing just a few dollars,” says project leader Aggelos Bletsas, a professor of electrical and computer engineering at the Technical University of Crete.

The network consists of several basic components: an existing FM radio station, an antenna (天线) attached to a lemon growing on a tree, a humidity (湿度) sensor in the lemon, a transistor connected to an antenna and an FM receiver. First, the antenna picks up the signal from the FM station, and then passes the signal to the transistor, which is modulated by the humidity sensor. The sensor switches the transistor on and off at a rate dependent on the plant’s moisture level: if the soil is wet or if the atmosphere is humid, that rate is lower; if it is dry, the rate is higher. Finally, the antenna broadcasts this information to the radio receiver on a mobile phone.

In this way, plants can tell farmers if they are thirsty. “We can literally ‘listen’ to the moisture of the plant, using our mobile FM radio with a $3.4 sensor,” Bletsas says. “Two of these sensors for every acre on any given farm might change the way we conduct agriculture and ‘understand’ plants.” He notes that more sensors may be needed for the best possible results. Such real-time information could enable better control of air and soil moisture.

Why go through all this trouble and not just use already common wireless technology, such as Bluetooth? “Not only is our technique less complex, as we are just borrowing signals in the environment,” Bletsas says, but “a Bluetooth-based sensor costs about $25. Our final aim is to launch sensors onto the market costing less than $1.”

“Bletsas and his team are completely changing the way of environmental sensing using very simple equipment and surprisingly little power,” says Alexandros Dimakis, an associate professor of electrical and computer engineering at the University of Texas at Austin, who was not involved in the research. “Their work could be a transformational Internet of Things technology for agriculture and for monitoring the environment.”

Bletsas and his colleagues have already applied for a patent for their innovative technology in America.

1.The radio network created by Greek researchers _________.

A.consumes much energy

B.can be put in a smartphone

C.uses simple technology at low cost

D.broadcasts radio programs to plants

2.What does the underlined word “modulated” in Paragraph 3 mean?

A.Monitored. B.Adjusted.

C.Measured. D.Connected.

3.What is Alexandros Dimakis’ attitude to the “radio network”?

A.Positive. B.Critical.

C.Neutral. D.Doubtful.

4.What is the purpose of the passage?

A.To discuss methods of studying plants.

B.To assess the efficiency of Internet of plants.

C.To stress the importance of keeping soil’s moisture.

D.To introduce a new way of measuring plants’ water use.

A team of researchers in the UK has shown that children who were taken to the library more often and owned more books at two years old achieved higher scores in school tests when they began primary school. The research also showed that although social background has a noticeable effect on a child’s readiness for school, attending pre-school and having their parents teach them a wide range of activities have a positive effect---while extended exposure to television lowers their scores.

“One message coming through loud and clear is that how a child learns in his very early years is critical (至关重要的) for a smooth transition into the educational system,” said Professor James Law. “This is a very positive message, as it gets us away from the belief that a child’s educational future is pre-determined by standard measures of socio-economic disadvantage, such as income, housing, or the mother’s education.”

Data from the study shows that children from a positive communication environment had a better expressive vocabulary by their second birthday. These children went on to achieve higher scores in language, reading and maths tests when they entered school. In the early years, the communication environment was a better predictor of children’s success with language than their general social background.

Most children develop speech and language effortlessly, but some are slow to acquire these skills and go on to struggle with literacy (读写能力) and academic skills throughout their schooling. This project set out to uncover what factors contributed to these problems.

Professor Sue Roulstone said, “These findings are an encouragement to all parents to provide a positive communication environment for their children from the very start of their lives. The project did identify particular aspects of the communication environment, such as having children’s books around and not having the television on too much. But the main message is that, as parents, we can have an impact on how our children learn to talk by providing a range of communication experiences. And the better our children are at talking by the age of two years, the better they will do when they start school.”

1.According to the passage, what is the most important factor contributing to children’s success at school? _____.

A. Their general social background.

B. Being taken to a library as early as possible.

C. Being involved in various activities.

D. Their communication environment.

2.From the research, Professor James Law concluded that _____.

A. children could naturally have a smooth transition into the educational system

B. the very early years had a big effect on children’s school performance

C. communication with children after they were over two years old was more effective

D. children’s educational future was pre-determined by their parents’ social position

3.The study shows that two-year-old children who have a positive communication environment do better in _____.

A. maths            B. reading

C. writing            D. speaking

4.What is implied in the passage? _____.

A. The research could help children who suffer from learning difficulties.

B. Parents should take their children to school as early as possible.

C. Teachers should teach children how to communicate with their parents.

D. Children who have good language abilities will not have difficulties in class.

5. People can most probably find this passage in the _____section of a website.
